Thanks for reporting this issue – sound rather severs – I bumped the priority
to blocker.

> Memory Leak When Logging Is Disabled In InMemoryTimeOrderedKeyValueBuffer
> -------------------------------------------------------------------------
>
> Key: KAFKA-13939
> URL: https://issues.apache.org/jira/browse/KAFKA-13939
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Jackson Newhouse
> Priority: Blocker
>
> If `loggingEnabled` is false, the `dirtyKeys` Set is not cleared within
> `flush()`, see
> [https://github.com/apache/kafka/blob/3.2/streams/src/main/java/org/apache/kafka/streams/state/internals/InMemoryTimeOrderedKeyValueBuffer.java#L262.]
> However, dirtyKeys is still written to in the loop within `evictWhile`. This
> causes dirtyKeys to continuously grow for the life of the buffer.
